I must be missing something (WinXP Pro). After reading about hidden administrator accounts, I restarted my computer in safe mode and the welcome screen showed icons for my usual account and an administrator account. Passwords were required for both and they were the ones that I specified when 1) I specified the administrator password during installation and 2) the password I set for my user account under user accounts. Also, the account names and passwords are the same as given in Control Panel -> Administrative Tools -> Computer Management -> Local Users and Groups -> Users.

This is how Win2K works and it makes sense to me. Where is this secret administrator's account and how do I find it??
